To all whom t may concern: v

Be it known that 1JOHN` E. BRADLEY, a citizen ofthe United States,residing at Fort Smith, in the county of Sebastian and State ofArkansas, have invented certain new and useful Improvements in Tobacco-Pipes, of which the following is a specification.

This invention relates to tobacco pipes, and more particularly to a pipeof that type inwhich the suction or smoke openings are positionedadjacent the upper end ofV the pipe bowl. f

One of the main objects of the vinvention is to provide a pipe of thecharacter stated of simple construction and operation provided with acasing or magazine from .which tobacco may be supplied directly to theinterior of the pipe bowl. A further object is to provide means forexerting constant upward pressure on the tobacco contained in the pipebowl so as to gradually force the same toward the upper end of the bowlas it is consumed. A still further object is to provide a pipe havingthe suction openings so relatively disposed as to insure even burning ofthetobacco. Further objects will appear from thedetail description.

The cylindrical bowl 1 of the pipe is provided, lat its upper end, withan internally threaded enlargement which receives the eX- ternallythreadedneck 2 of the fire bowl 3. The lower end of this yneck ts snuglyagainst the upper face of the annular shoulder contiguous with the innercylindrical chamber of bowl 1 so as to effect a tight closure therewith.The re bowl 3'is`pr-ovided with an external annular shoulder 4, and, atits upper end, with an inwardly 'directed annular shoulder 5 which isconcentric with the frusto-conical opening at the top ,of the fire bowl.The fire bowl is further provided with a plurality of downwardly andoutwardly inclined smoke ducts 6. These ducts communicate with theYinterior of the re bowl a short distance below the annular shoulder 5.There are four of these ducts in all, and they are spaced 90Q apartabout the tire bowl, the ducts of one side of the fire bowlcommunicating at their lowerends with a horizontal groove 7 formed inthe upper face of the smoke collecting ring 8 which is threaded aboutthe neck 2 of the tire bowl between the upper endof pipe bowl 1 andshoulder' 4:. -The two ducts at the other side ofthe tire bowlcommunicate with a similar groove 7a in the upper face of smokecollecting ring 8. Each ofthese grooves is connected by a vertical duct9 with `an approximate semi-circular groove 10 formed in theunderfacejof smoke collecting ring 8. This groove 10 communicates with avertical smoke passage 1l extending downward in the wall of pipe bowl 1which communicates with a smoke passage 12 formed in a neck 13 of thepipe bowl. Neck 18 is threaded to receive the usual stem 14. By thismeans smoke may be drawn from the re bowl through the stem, and thissmoke is taken from four equally spaced points within the tire bowl,thus insuring even burning of'thecontents of this bowl. A short by-pass15 communicates with thesmoke passage 11, 'atits juncture with the smokepassage 12.l This bypass is directed downwardly and outwardly and isnormally closed by a stopper 16. The by-pass 15 provides .a collectingchamber for any nicotin or tobacco juice which may get into the smokepassage, and these accumulations can be quickly and easily removed byVremoving stopper 16 from the pipe bowl.

A tobacco holding chamber or magazine 17 is secured to the front ofubowl1 and communicates with the interior thereof through a slot or passage18. This magazine is provided, in each side near the outer edge thereof,with a longitudinally extending groove 19. These` grooves are adapted toreceive the turnedover flanges 20 of a sheet metalV cover .21 so as tosecure the same slidably on the magazine. The upper end of this cover isturned over to provide a flange 22 which engages the top of magazine 17thus preventing the cover `from moving?,- dQWIl.- ward from in front olithe magazine.l As will be evident, the cover may be raised, whendesired, so as to open the magazine.

A metal cylinder 23 open at both ends fits snugly within the cylindricalinterior chamber of bowl l. This cylinder is provided, near its lowerend, with a groove which receives the inner end of a catch 2stApivotally mounted on the bottom of pipe bowl l by means of screw post25. rllhis catch acts to normally hold the cylinder within the pipebowl. Cylinder 23 is of such length that, when in operative position, itextends to the inner end of neck of the lire bowl. This cylinder isAprovided with a longitudinally extending slot Q6 which is normally inregister with passage 18 of magazine 17.

Y fr cylinder 27 tits snugly within the cylinder 23 and is open at itsupper end. This cylinder is secured in adjustment in cylinder 23 bymeans of a set screw 2S threaded through vcylinder Q3 and engagingcylinder 2'?. The lower end of cylinder 27 is closed by a disk 29secured therein. A. head 30 is slidably mounted in the cylinder 27 andlits snugly within the same. This head is forced upward by means ofacoil spring 31 confined between ythe same and disk 29. ri rod 32 issecured through head 30 at the center thereof and is slidable through anopening through the center of disk 29.

'ln using the pipe, the cylinder 27 is drawn downward, after releasingthe same trom set screw 2S, so as to uncover the slot 26 of cylinder 23.When this has been done a suitable quantity of tobacco may be forcedfrom the magazine 17 into the pipe bowl, the head 30 being drawndownward by means of rod 32, this tobacco falls into the cylinder 27above the head. When a suitable chargey has thus been forced intocylinder 27, this cylinder is returned to position to shut olicommunication between the pipe bowl and the magazine. The spring 81 willact by expansion to torce head 8O upward thus forcing the charge ol?tobacco into the lire bowl 3. This tobacco will engage the annularshoulder 5 at the upper end of `the bowl which will prevent the tobaccofrom being forced entirely out of the bowl. The top of the charge isthen ignited in the usual manner, the smoke passing downward about thelire bowl into the stem 11i. As the tobacco is burned., the ash producedwill Vhave very little resistance and will thereiore be forced upwardout of the top of the bowl permitting the tobacco within the pipe bowlto be gradually forced upward as it is consumed. By this means the smokeis taken from the top portion of the tobacco charge and does not passdownward throughV a relatively large mass of tobacco as in the commonform of pipe. This prevents, to a large extent, excessive heating of thetobacco Within the pip@ bowl thu-S eliminating the creatiQll oi' largequantities of nicotin within the pipe. By adjusting the cylinder 27within cylinder 23 the pressure on the tobacco within the pipe bowl maybe adjusted as desired.

`When Vit is desired to clean the pipe bowl the cylinders 23 and 27 maybe quickly and easily removed, as may also the lire bowl 8. This leavesthe pipe bowl in the form of a cylinder open at both ends thuspermitting ready access to the interior of the same.

The modified form shown in Figs. G to 8 of the drawings is very similarto that shown in Figs. Ito 5. lin this form the `re bowl 3 is replacedby a ring 33 provided in its outer facie with two ,diametrically oppoitevhorizrnital.grooves Sil which communicate at their ends with theinterior of the `ring through ports 35. Each'of the grooves 3a isconnected by a vertical passage 36150 a horizontal passage 37 whichcommunicates through a short vertical passage 38 with kthe smoke passagell of pipe bowl 1. The action or' this imodiiied form of pipe is similarto that previously described in connection with the term shown in Figs..1 to 5 of the drawings, the `smoke ring i0 being replaced by a sleeve 39which fits snugly about ring 33. This sleeve acts to coniine the smokeand cause the same to flow downwardly into the smoke passage and thenceinto the stemofthe pipe.

There may be slight changes made in the construction' and arrangement ofthe ditier- 100 ent parts of my linvent/ion without departing :from theiield and scope of the same, and l intend to include all suchvariations, as fall within the scope of the appended claims, in thisapplication in which a -pre- 105 ferred form only of my invention isdisclosed.
